Two specific GUT BACTERIUM identified as precursors for MULTIPLE SCLEROSIS

August 06, 2025 - bacterium from the Firmicutes phylum, this strain is associated with MS in twin studies. It thrives in the small intestine, where it ferments dietary fibre into short-chain fatty acids (e.g., acetate, propionate). While SCFAs typically foster regulatory T cells (Tregs) to curb inflammation, in MS, E. tayi’s metabolites may instead promote Th17 cells—pro-inflammatory agents implicated in autoimmunity. Research suggests E. tayi might degrade mucin, compromising gut barrier ...

Bacterium shows promise for producing solar fuels through artificial photosynthesis

January 31, 2019 - bacterium and activate various enzymes. The resulting reactions lead to the process called carbon dioxide reduction.

Carbon dioxide reduction converts the gas into acetate. This chemical is an important ingredient in solar fuels.

This extracellular model suffers from low quantum efficiency. If the nanoparticles are mounted outside the cell, not all of the electrons they produce will reach the chemicals involved with carbon dioxide reduction. These electrons end ...

Unexpected freshwater bacterium found in ocean reveals hidden land-to-sea highway

October 25, 2025 -

In a discovery that reads like a microbial mystery, researchers at the University of Hawaii at M?noa have identified a new species of bacteria that shouldn't exist where it was found, unveiling a hidden pathway connecting Hawaii's land and sea.

The bacterium, named Caulobacter inopinatus, was unexpectedly discovered in seawater from O'ahu's south shore. This finding is groundbreaking because it is the first known species from the Caulobacter ...

Ancient ice cave bacterium frozen for 5,000 years shows resistance to modern antibiotics

a month ago -

A bacterium frozen in time for five millennia has delivered a chilling message to modern medicine. Deep within a Romanian ice cave, scientists have awakened a microbial relic that shrugs off some of our most potent antibiotics, proving this global health crisis is a natural phenomenon humanity has dangerously accelerated.

Researchers drilling a 25-meter ice core in the Scarisoara Ice Cave uncovered a bacterial strain called Psychrobacter SC65A....

Stomach bacterium linked to Alzheimer’s: How H. pylori could raise your dementia risk

September 19, 2025 -

Alzheimer's disease, a devastating neurodegenerative condition affecting over 55 million people worldwide, has long puzzled scientists searching for its root causes. While genetics, toxins and lifestyle factors have been implicated, new research suggests an unexpected culprit lurking in the gut: Helicobacter pylori, a bacterium present in one-third of the global population. A groundbreaking Canadian review published in Alzheimer's and Dementia ...

This humble bacterium could rewrite the rules of dental health, preventing gum disease

September 04, 2025 - bacterium lactis HN019. In a randomized, double-blind, placebo-controlled trial — the gold standard of medical research — scientists gave 60 adults with gingivitis either a probiotic lozenge or a dummy pill twice daily for eight weeks. The results were stark. Those in the probiotic group didn’t just see less plaque (though they did). They experienced a dramatic reduction in gum bleeding, lower levels of inflammatory chemicals like IL-1?, and — most striking — nearly ...

Conan the Bacterium: Researchers study microbe that can withstand extremely high radiation doses

December 16, 2024 - bacterium combines a simple trio of ingredients — manganese ions, phosphate and a small peptide — to form a powerful antioxidant that protects it from the harshest conditions. (Related: Microbe found in Ethiopian volcano’s strongly acidic saltwater hints microorganisms could have survived in similar conditions on Early Mars.)

Scientists have now isolated and synthesized a designer antioxidant called MDP, made from manganese ions, phosphate and a small peptide.

Does the bacterium that causes Lyme disease also hold the key to treating Lyme arthritis?

February 06, 2020 -

A study published in the journal Proceedings of the National Academy of Sciences of the United States of America found that B. burgdorferi peptidoglycan, a major component of the cell wall, acts as an immunogen that contributes to inflammation during Lyme infection and in cases of post-infectious Lyme arthritis.

“This discovery will help researchers improve diagnostic tests and may lead to new treatment options for patients suffering from Lyme arthritis,” said lead ...

Testing for a commensal gut bacterium could help identify people at risk of severe COVID-19

February 04, 2021 - bacterium and opportunistic pathogen that can trigger inflammatory bowel disease (IBD). This suggests that the bacterium is a reliable predictor of COVID-19 disease severity. E. faecalis can easily be collected from stool samples and grown in laboratories – thus, the researchers propose that COVID-19 patients be tested for this bacterium.

"Enterococcus faecalis is already easily cultivable in clinical laboratories, as such we urge the medical ...

Study reveals marathoners and elite athletes have high levels of gut bacterium that improve exercise endurance

March 23, 2020 -

The findings come from a study involving 15 athletes who participated in the 2015 Boston Marathon. According to the authors, these athletes had higher-than-normal amounts of a gut bacterium from the genus Veillonella.

The researchers discovered the presence of the bacterium after taking daily samples of solid waste from the athletes one week before and one week after the marathon. The microbe known as V. atypica was present in larger numbers in the digestive ...

Scientists identify unique bacterium in the microbiomes of elite athletes that can improve the exercise capacity of sedentary people

April 14, 2020 -

Scientists at the Joslin Diabetes Center, in Boston, are looking at the bacterium from the genus Veillonella and how it helps give athletes an extra boost of endurance. The researchers believe that the bacterium could be used in a probiotic supplement that could help those who struggle to exercise, such as Type 2 diabetics.

The researchers are pulling from a study begun in 2015 when a team from Harvard Medical School found V. atypica in larger than normal ...

Is this why kids are so happy? Researchers discover anti-inflammatory fat in soil-dwelling bacterium that can help relieve stress

July 13, 2020 - bacterium exerted anxiety-reducing effects similar to antidepressants.The anti-stress and antidepressant-like effects of Mycobacterium vaccae

Lowry and his team's earlier discovery led them to speculate that M. vaccae may harbor certain compounds that can reduce stress and inhibit inflammation in the brain. (Related: Prolonged intense stress can SHRINK your brain.)

To test their hypothesis, Lowry and his colleagues used gene-sequencing technology to ...

Doesn’t stomach acid eat bacteria? Researchers successfully identify the hiding place of H. pylori, a bacteria linked to stomach ulcers, cancer

November 06, 2019 -

It is said that about half of the entire human population plays host to H. pylori, but not much is known about how this bacterium manages to colonize and persist inside the human stomach. In a new study published in the journal PLOS Biology, researchers from the U.S. and the U.K. addressed this by investigating the behavior of H. pylori in the stomach of mice. Using high-resolution imaging and mapping techniques, they were able to observe and present a new model of ...

Scientists sniff out new treatment for Alzheimer’s; new research suggests brain cells can be protected by stimulating the sense of smell

November 15, 2017 - A study published in the journal Science Signaling has revealed that teaching roundworms to sniff out a certain type of bacterium has led them to develop a defense mechanism to preserve their brain cells. The findings show potential as a drug-free intervention against neurodegenerative diseases such as dementia and Huntington's disease, the researchers have stated.

The scientists have noted that roundworms only have 302 neurons compared with the billions seen in humans, ...

Ticks and the growing threat beyond Lyme disease

5 days ago -

Moving on to Lyme disease, ticks present a significant threat not only to human health but also to our pets' well-being. These tiny creatures are more than just nuisances; they represent a serious medical concern due to their ability to transmit dangerous pathogens. The bacterium Borrelia burgdorferi, which causes Lyme disease, is a primary concern. It's estimated that around 476,000 Americans are diagnosed and treated for Lyme disease annually. The ...
